Onoff

? I remember some louts years ago doing it to the fountains outside the leisure centre in Dartford! I was suggesting it half seriously. The Kamco manual refers to adding an anti foaming agent to some of their products. Off then to measure a kilo of citric acid and boil some kettles! No need to neutralise after with say bicarbonate of soda or something similar?

But will it do any good is the question? Half debating slinging a dishwasher or wm tablet in the reservoir.....

Brother in law

Talking of pressure, I tried earlier to fill the system via the boiler drain cock before turning on the PFM. The 8bar garden hose pressure was too much for the O ring around the spindle of the drain cock for a start. Then one of the fittings came apart on me... Still at it here. It's coming out a bit brown again. I've a few kg of citric acid sitting here. No bulk hot water available of course but I could dissolve some in a kettle or two full and sling that in the PFM tank. Worth doing? A little worried about neutralising the acid thereafter. I've still got the rad to fit later/tomorrow.

@zoothorn, I've your address somewhere but it means going back through years of pms. PM me again your post code and I'll try and find some local places to you for bits of hardwood.

I was being quite serious about using felled wood and seasoning yourself. Nothing nicer imo. The BiL has a bloody great log sawmill on rails like a bandsaw on it's side. Came from Eastern Europe. Has a petrol engine on it. Makes loads of stuff.

The modern rads, 4 upstairs and one downstairs, all the rad valves are open. The old rads downstairs, the remaining 7, I can't move any of the valves at all:

It had 2L of Sentinel 400 stuck in last week and that's been running round (hot) since. All that got drained off earlier today. I've been running it back and forth and dumping it/refilling with clean water for maybe an hour, seems longer. The PFM tank is now clean as is the dump water. Dumping into a washing up bowl on the patio so I can gauge how clean it is. To start with it was jet black. Can't find my rubber mallets (neither of them) so it was a wooden mallet wrapped in a T-shirt. Thinking if it's running clean then time to stop maybe? The rad valves...no not fully open, will go and do that now and carry on. Little video:

What about that forest they've just felled near you? You'd have to season it mind.

So all cleaned up and turned on. I have no idea what I'm doing with this! ? I filled the system from the header as best as. I then closed the balancing valve on the coil. Because the PFM was in circuit it's tank filled up from the header so it was a bit black! I then turned on the PFM. Back and forth, back and forth reversing direction. Had one leak where I connected the hoses to the IntaKlean2 connection. I then turned it onto dump, came out rotten. Only so much water dumps, when it slows to a trickle I switch it back to recirculate. Repeat. Periodically I'm topping the tank up from the garden hose. The water in the tank is getting cleaner I think. I'm just carrying in doing that. Could be a long cold night! ? One pita though. I initially closed the balancing valve on the return of the coil. After having run through the CH circuit I slowly turned the balancing valve on. Bloody thing is leaking and I don't have another (28mm) anything I can do? Cheers

Who's clever f***ing idea was it to fill from the boiler drain off? Hilarious when the hose comes apart at 8bar... indoors... ? I am now wet, cold with obviously no heating or means of having a shower. System is drained down. F*** IT, going to fill the tank of this PFM and switch it on.

Old 28mm pump olives multi tooled off. New valves on. Going to refit the header tank now. Not all going quite as quick as I'd hoped mind!

Thanks. Connecting the PFM here: A more immediate problem is the pump valves. Got those you recommend. One was a bitch to get off the pipe, I nearly pulled something! ? The 28mm olives have to come off now. Thinking multi tool with a bi-metal blade. Only got a 15mm olive tool. The crud in there but it is at least loose seemingly!

Mucky header tank removed after loosening sone associated pipe work. Jet washed and filled with a strong citric acid / hit water solution to get rid of the ingrained rust stains! Found the lid too when I removed it! Pump valves next I think. Not sure when to fit the new rad. Now or after the power flushing and another drain down? @PeterW when I back fill via the boiler drain I presume have the PFM connected up & all zone valves open? Should I also have the feed to the header open? Thinking when the system is "full" I'll see water coming out the overflow. Thanks.

Are you going to just make a braced door or a braced and framed door? Shuts will either sit against the boards facing the door or the braces. I made a braced stable door for a freebie shed out of scrap. I just routed grooves in the edges of the rough 4x2 and used ply strips as tongues.

Don't be surprised when you hang the door if it's flush one side where the hinges are and not the other where the latch is, either out at the top or bottom. A laser is tbh better imo to plumb frames in than a spirit level. Cross that bridge if and when we come to it! When you pin your shuts on: -Shut your door. -Do the head shut first then the sides. -Cut all to length. -Slip 1mm packs between door and shut, allows for paint thickness -Pin shuts using (supplied?) panel pins but don't knock them fully home until satisfied as to how the door closes -Punch them just below the surface, fill and paint

Couple of pics of the underlying detail where the LED strip is: 2 strips of ply to give depth: Then a capping piece. Sort of forms a shelf the LED channel sits on. Tbh it's sat up there "loose" 'ish: Back to back trim on the capping piece: When you're lying in the bath you can't see the strip, you just get a "glow" washing the mosaics.

Damn! I totally forgot about the state of the header tank. Through I guess general crap in the incoming mains water, the occasional pump over in the past coupled with no lid, it's filthy. Full of rust and scale by the looks of things. This shot was taken by holding the phone over the top. Access is appalling as I think previously mentioned. If I'm going to do all this cleaning it's pointless not doing the header tank too. Don't want to be reintroducing unnecessary crap into the system if I can help it. Think I can squeeze it out of where it is if I disconnect mains in, out and the expansion. First problem is the stopcock on the incoming mains is seized solid. At least removing the tank I'll be able to get to the manky end of that expansion pipe to clean it up and fit a temporary stop end. Oh well, nobody's going to sort this but me! ?

I'm wondering whether I should first isolate the downstairs single pipe system, which I can quite easily as I've a ball valve on the flow and return? I could then flush the upstairs flow and return system on its own.

Should that ever happen I'll let you know!

I like that idea. Rough plan of attack then: -Coffee & bagels ? -Isolate mains power -Close ball valve on feed from header tank -Hose on boiler open drain -Hose on d'stairs CH single pipe system open drain -Drain down -Close drain on d'stairs single pipe system -Refill via boiler drain from mains hose -Cap off expansion -Put mid position to MAN -Put 2 ports to MAN -Close balancing valve on return from coil -Remove IntaKlean2 from 28mm return pipe -Connect ScaleBreaker to pipe ends -Run drain line -Attach mains water to ScaleBreaker -Fill ScaleBreaker tank -Switch on That's as far as I've considered so far.

PFM is going to sit in the boiler room between boiler and back door. Hoses aren't long enough to go outside. Nearest window is fixed glazing. I'll somehow extend the drain to outside though.

There are no instructions per se for this ScaleBreaker C90 when using it for power flushing. All that's in the manual is how to use it to descale. Do I drain the system first as in boiler, rads, coil etc then fill the unit or leave what's in there, well, in there and just start pumping it round both ways, then dump it?

Just been in there for a shower in the wet room corner.....15degC. Not saying it's cold but a polar bear ran OUT. Please, take her.
